What is DCT?

Dynamic Contraction Technique (DCT) is a methodology that uses eccentric muscle contractions to breakdown scar tissue. Scar tissue is abnormal unions of connective tissue in the body that form after trauma and can affect skin, muscles, ligaments and tendons. Nic Bartolotta developed the technique based on the idea of muscle tension and strategies to reduce knots within the muscles. The goal of the DCT methodology is to reestablish muscle function and improve flexibility through lengthening the active muscle under a load which is called an eccentric muscle contraction. The idea is that the eccentric contraction helps pull apart some of those muscle fibers that become knotted together creating a “tight” muscle. DCT incorporates a balance of resistance stretching and strength training that combines principles from modalities across the world in order to improve performance, reduce injury risk, and improve quality of life conditions by establishing better muscle function and reducing chronic discomfort from tight muscles.

Why and When would you use DCT?

DCT can be used for anyone. Infinity Sports Institute will apply DCT techniques on a case by case basis following a consultation and/or an evaluation. The techniques are used routinely to address injuries and for developing performance programs based on the individual’s goal. The idea of DCT simply put is to strengthen the weak tissues and expand the strong tissue.  This happens by doing an eccentric muscle contraction, or by placing a load on a muscle that is being stretched and lengthened. An example of an eccentric contraction would be instead of performing a normal biceps curl up towards their chest, they slowly resist against the weight as it lowers back down away from their chest.

The Takeaway

Practitioners and clients using DCT’s methods are able to improve stability in the body, by improving movement and how the body is able to handle wear and tear. DCT’s methodology is a great resource to utilize when applied appropriately and correctly. If you have been having mobility issues and feeling tons of different knots then DCT might be for you.

Infinity Sports and Dari Motion

DARI Motion

Biomechanics play an important role in health, wellness, workplace health and safety, performance and research of the body. You might be asking, what are “biomechanics”? Well, biomechanics is the study of the mechanical laws relating to the movement or structure of living organisms.

As an active individual whether you’re an athlete, weekend warrior, fitness enthusiast, or your job is physically demanding; the study of your biomechanics can help solve issues that may or have already caused injury or pain.

What is DARI Motion

DARI Motion is a markerless motion capture system used to acquire the most precise, accurate and comprehensive biomechanics data in the industry. 

Due to its industry leading precision and accuracy the DARI Motion is able to track changes over time with sub-millimeter accuracy. This provides us with accurate information needed to make immediate, informed decisions to adjust and guarantee each rehab, performance or recovery program is meeting your exact needs and our expectations. 

The Dari Motion Tracks: 

  • 21 bone segments, nine joints, with six-degrees of freedom
  • Kinematics and kinetics in all planes
  • Range of motion
  • Joint torques
  • Internal/external rotation at the hip
  • Shoulder ab-duction
  • Anterior/posterior coronal deviation
  • Neuromuscular engagement, center of mass sway in all planes
  • All joints in space

DARI’s patented, 3rd-party validated kinetic capture collects kinetics without force plates. That means DARI can measure joint torques, ground reaction forces, and other force measurements without restricting the subject’s natural movement.

Why We Chose DARI Motion

Dari Motion is the Gold Standard and the most advanced, precise and accurate motion capture system. In order for us at Infinity Sports Institute to provide our athletes, patients, clients and members with the remarkable care, programs and outcomes we require industry leading technology and data.

The DARI Motion can be found at The Infinity Sports Institute Sports Science Lab, the only Sports Science Lab available to the public outside a University setting, in South Florida.

DARI Motion Accuracy

Most other markerless systems use a single consumer-grade depth camera originally developed for console gaming. These lack accuracy, capture a limited amount of the body, and can’t capture explosive, high-speed motions at their native 30 hz framerate.

Traditional motion labs require manual application of reflective markers on the body, causing up to 20% marker-placement error between sessions. Marker-based systems can not accurately track biomechanical data over time.

DARI uses eight high-speed cameras placed around the subject and a state-of-the-art computer-vision engine to collect whole-body data–including the fastest motions.

DARI Motion Speed

Marker-based motion analysis requires up to 45 minutes of marker placement for every session. Traditional marker-based analysis of a single human motion requires days of intensive data compiling and error-correction. By the time the data has been processed, the window of application will have passed. Therefor we will not have the chance to make accurate decisions on time. 

The DARI Motion has zero markers and zero set up time. A complete body motion analysis takes under 5 minutes allowing us to scan 50 – 100 individuals per day! The DARI takes thousands of data points comprising each motion and processes them in under a second, that’s what we call FAST

Knowledge is Potential Execution is Power

Quantification of data is useless if there is no action. The Dari Motion Provides easy-to-read reports, which our Performance and Sports Science Lab teams can explain to a 1stGrader! These reports allow us to take action steps to improving your health, performance and reducing your risk of injury. These reports include: 

  • Muscle-mapping and injury vulnerability 
  • Custom scoring and dynamic narratives 
  • Data integration with other devices
  • Custom exercise suggestions
  • Single and multiple motion reports

Who should take advantage of the DARI Motion System?

The Dari Motion is used for Wellness, Workplace health, Performance and Research. 

Fitness Enthusiast, Average Person

If you are trying to improve or maintain health as well as mitigate any risks for potential injury. 

Employers

The DARI Motion capture platform can perform a comprehensive biomechanical analysis in as little as five minutes allowing you to efficiently screen your entire employee population for Musculoskeletal Disorder Risk and Musculoskeletal Injury Risk

Athletes and Team Organizations

DARI can collect objective, actionable biomechanical data on entire teams in a matter of hours giving athletes and training staffs the tools to transform their motion.

Competitive Athletes

Optimize Movement, Avoid Injury, Track Progress. As soon as an athlete steps out of the capture space, DARI delivers an easy-to-read report with actionable insights, allowing coaches and trainers to get to work immediately

Research Institutions

DARI’s robust motion capture allows research to be conducted on populations that are difficult to assess with traditional systems. The capture space can support implements, such as treadmills, stairs, cycles, and chairs, items that can be critical to research-specific assessments.

IT Band and Knee Pain? Might be your Butt!

The Gluteus Maximus 

IT Band Issues, Low Back Pain, Hamstring Injuries, Knee Pain, Hip and Knee Injuries, Lack of Performance, Loss of Balance, Running Slow, or worse – Seeing NO Gains? Is this you? Read Below. 

 

The Glute. Max.

Is definitely a nice muscle to look at and one of the most powerful muscles we have. Unfortunately many of us suffer from “Glute Amnesia”, the lack of this muscle to actually work. In rehab & performance this is a topic that is touched on quite a bit. If you’ve ever been to a good Therapist, Strength and Conditioning coach, or Performance Specialist, we bet they have checked if those “awesome to look” at muscles are actually working.  

You’re probably wondering, “Are my Glutes. Working?”… Well Probably not. We know, we know, you lift like everyday, run and you where a high school all star. But before we try and prove each other wrong lets go over the Gluteus Maximus.  

Why is your Butt so important?   

This awesome muscle definitely connects to many things at its origin and insertion – Imagine how it would make you feel if it’s sleeping on the job.  

At its Origin the Glute Max inserts into the Fascia of the gluteus medius; the external surface of the ilium behind the posterior gluteal line; the fascia of the  erector spinae; the dorsal surface of the sacrum; the lateral margin of the coccyx; the sacrotuberal ligament.   

At its Insertion the Glute Max inserts through the Upper fibers, to the posterior part of the iliotibial tract and the fasciae latae muscles; Through the Lower fibers, to the gluteal tuberosity of the proximal femur.   

did you read all that 🧐? If you didn’t here’s the quickie: 

The Glute Max inserts/connects with the Glute Medius, ilium, your lower back muscles, sacrum, coccyx, a ligament at the lower and back part of the pelvis, IT Band, TFL, and the femur.  

That’s a ton of connections and things that can have issues if your Glute Max is not up to par .  

Now that you know where it connects – here are its actions (what it does) 

It performs extension of the femur from the flexed position in the hip joint; lateral stabilization of the hip and knee joints; external rotation of the femur.   

The Glute Max helps you bring back the femur from a flexed hip position such as a deadlift, Romanian Deadlift, Running (extension of the hip). It helps us stabilize the hip and knee joints as well as helping us externally rotate the femur.  

We can definitely agree that this awesome muscle needs to be functional during all activities: walking, using the stairs, running, weightlifting, dancing, and making the magic happen  

Use it or Lose it!

You ever hear the saying “Use it’s or Lose it” well that is perfect when describing what happens to muscles that don’t get used properly. Your Glute Max is supposed to do many things, but, what happens if you sit on it for 8 hours, or your run looks more like a jog between mile 3 and 12 and you’re not going through a full running gait cycle? Unfortunately that really powerful muscle can become inhibited and atrophy. The under used Glute will recruit less motor units causing it to work less and eventually start shrinking : “You’re going to lose your Gains!”.  

In the previous paragraphs you learned where the Glute. Max connects and what it does. Now, if it’s inhibited,  it will cause energy leaks causing other muscles to absorb more energy and work harder as well. As the Glute Max atrophies it will cause tension in the areas where it connects.   

If the Glute is sleeping on the job, it can be a reason for the IT Band issues your experiencing, that constant tension and pain in your lower back, that lateral hip pain, or knee pain. A non functional Glute Max can also be a catalyst for an injury such as ligament tear/sprain, lack of balance and loss of performance.  

So,  is your Glue Max working? Properly? Don’t Know? Come Check us out, send us a message or book directly using the Link on this page!

Running: Strength Training To Improve Your Running Pt.1

Strength training for Runners

Strength Training is very overlooked and shied away from topic in the running community, as their are many myths, such as “Strength Training or Lifting Weights will make me slow”.  Strength training is a crucial component in keeping you healthy, strong, and running your best.

Runners love to run and base everything on running exercises. Here are some other famous quotes we’ve heard over the years;

“ I want to be faster let me run faster during miles”

“ let’s do fartleck instead”

” I need more endurance, let me add another mile”

And my favorite “ Weight training, won’t make me faster or let me run more”.

Can Strength Training Really Help Me?

By actually adding some form of  resistance training, whether it is maximal strength or endurance training time to fatigue will decrease, rate of force production will decrease ( this is good) and overall run time will decrease. Almost forgot to mention, impact absorption also increases which decreases the chances of injury.

One great study on this was on maximal strength training by kyvind stkren of Norway1. Their program was 24 sessions over a 8 week period, 3 days a week of 4 sets of 4 reps of half squats. At the end there was an increase of rep max of 33%, rate of force production of 26%, rate of exertion by 70%, time to exhaustion increased by 5%, but there was no correlation to vo2 max (this is normal when performing tests that do not change intensities, not a graded test).

Another study we’ll mention did a training program using both strength and endurance which showed  improvements in time to exhaustion2

In short, by adding a resistance training program that is focused on power development  and velocity it will dramatically increase a runners speed and time to exhaustion ( endurance, Lactic acid tolerance). This also lessens the increase of mass(weight) and focuses more on the neuromuscular adaptions needed for power.

Running: Using RockTape To Improve Your Running !

Using RockTape To Improve Your Running

I am sure you have seen a numerous amounts of athletes on TV rocking this cool looking tape on their shoulders, necks, backs and other areas. From Olympic Swimming to NBA or the NFL, athletes of all kinds are enjoying the benefits of this tape.  I’m sure you’re wondering how it can help your running, right? But, before we explain how it can be used to improve your running, let’s find out what it is.

So what exactly is RockTape?

RockTape is a Kinesiology Tape preferred by many due to its high quality, pliability and great adhesive. RockTape is made from 97% Cotton 3% Nylon; with a hypo-allergenic, acrylic based adhesive that’s free of latex. This allows RockTape to outperform the competition by being stretchier and stickier.

But what is Kinesiology Tape?

Kinesiology Tape was developed in the 1970s by Dr.Kenzo Kase, from Kojimachi, Tokyo,as a way to prolong the healing effects of his treatment for his patients through the skin.

Kinesiology Tape is not like Athletic Tape. Athletic Tape is meant to be rigid, restrict motion and add support, as where Kinesiology Tape is meant to be flexible not restricting and assist in mobility, plus more!

RockTape can be used in many ways for multiple benefits.

  • To Relieve Pain
  • To Activate or De-Activate a Muscle
  • To Reduce Swelling
  • To Delay Fatigue
  • To Decompress
  • To Enhance Movement and Improve Posture

 

My run was amazing!! The tape was great I attribute he comfort of my run to the rock tape!!! You guys…. Rock!!
Mary Hussey – 2018 Miami Marathon participant

Improve your running

One of the major issues with runners is that lingering discomfort or pain. RockTape can be used to help with that knee, hip or lower back pain by altering the pain signals to the brain changing the way your body perceives the pain. It can do this by lifting the skin and decompressing the area where pain or discomfort is present (as shown in the image above).

That constant Knee pain/discomfort can actually be caused by energy leaks(click here for previous post on energy leaks) due to inefficient biomechanics. A great example of this is knee pain caused by an over-pronating foot. You can use RockTape to temporarily correct the medial collapse which can improve that knee pain/discomfort as well as improve your gait! This is done as the RockTape will provide Kinesthetic Guidance (tactile stimuli providing feedback to the brain on how to move) so you can move more efficiently.  The RockTape acts as a physical cue to better enhance a movement pattern (as shown below)

Swollen Knees or Ankles?

No worries, RockTape can be used to help assist the lymphatic system by draining lymphatic fluid! This will not only help reduce swelling but it also helps with bruising!

 

RockTape can be used in so many different ways to help improve your running. Although the taping looks simple only a trained professional is able to determine why it’s needed, what needs to be taped and how it should be taped. The why, what and how are crucial in achieving a dramatic and positive effect.
